Recordnotfound How to internationalize?

The exception messages for recordnotfound appear to be
"Couldn’t find with ID=xxx "
“Couldn’t find without an ID”

These are exactly what I need, except I need them in multiple
languages. Are there translations of this type of stuff or translation
keys. I have a whole lot of default AR translations and keys
(courtesy of svenfuchs i18n on github) but these are only for
validation errors of attributes (on write). I can find nothing for

Any help greatly appreciated.
